A boolean specifying whether to retrieve the full list of objects for
this year and pass those to the template. If True, the list of
objects will be made available to the context. If False, the
None queryset will be used as the object list. By default, this is
False.

In this example, you are outputting the week number. Keep in mind that week
numbers computed by the date template filter with the 'W'
format character are not always the same as those computed by
strftime() and strptime() with the '%W' format
string. For year 2015, for example, week numbers output by date
are higher by one compared to those output by strftime(). There
isn’t an equivalent for the '%U'strftime() format string
in date. Therefore, you should avoid using date to
generate URLs for WeekArchiveView.

This view uses by default the same template as the
DayArchiveView, which is in the previous example. If you need
a different template, set the template_name attribute to be the
name of the new template.
